Babylon 5: Thirdspace Plot Summary

Read the complete plot summary and ending explained for Babylon 5: Thirdspace (1998). From turning points to emotional moments, uncover what really happened and why it matters.

An enormous artifact is discovered in hyperspace and is towed to Babylon 5 for investigation. The xenoarchaeology corporation Interplanetary Expeditions sends a representative, Dr. Elizabeth Trent, Shari Belafonte to take control of the artifact’s examination.

The artifact begins to influence the dreams of many inhabitants of Babylon 5, eventually controlling many of them during their waking hours as well. These thralls, led by Deuce, William Sanderson first demand that the excavation be accelerated, and then become increasingly violent toward the rest of the Babylon 5 population. Dr. Trent conjectures that the artifact is a Jumpgate that takes one neither to normal space nor to hyperspace but to a third space (hence the movie’s title). With the reluctant support of her colleague, they order the device to be turned on, without notifying Captain Sheridan, Bruce Boxleitner.

Sheridan and Delenn, Mira Furlan visit Lyta Alexander, Patricia Tallman who, transmitting a “race memory”, explains that the gate was built by the Vorlons a million years ago with a purpose that cannot be expressed in human terms except as an attempt to make contact with the gods. The Vorlons discovered that Thirdspace is a parallel universe inhabited by a violent, telepathic alien species even older and more powerful than the Vorlons that is bent on exterminating all life other than their own.

Long ago, the Thirdspace aliens telepathically converted a small army of Vorlons to fight and die for them. The ensuing battle ended in a stalemate; the non-thrall Vorlons shut down the gate, but the remaining Vorlon thralls prevented the artifact’s destruction by sending it into hyperspace where it was lost but preserved (in hopes that it might one day be reawakened). Lyta then telepathically informs Captain Sheridan how to deactivate the gate.

When the device is finally reactivated, the Thirdspace aliens stream out from the portal in small fighters and begin a devastating assault on Babylon 5, obliterating large cruisers with little effort. The Thirdspace fleet is highly advanced and the single-occupant fighters possess deflector shield technology, making them extremely hard to destroy. The violent behavior of the individuals under the artifact’s control is intended to disrupt the station’s defenses. The struggle is ended when Sheridan uses a thermonuclear device to destroy the artifact just as the first wave of Thirdspace heavy warships begins to emerge. Once the artifact is destroyed, the telepathic influence stops and the station returns to normal. Trent, shaken by the way in which the artifact affected her, turns over her final report and goes on an indefinite hiatus.

Sheridan and the others conceal the true nature of the artifact from those who ask questions and confidently assure themselves that the incident is unlikely to occur again. In private, Lyta broods with the knowledge that the artifact was only one of many mistakes the Vorlons have made.

Discovered in hyperspace; en route to Babylon 5 Hyperspace

Artifact begins to influence minds

The artifact begins to influence the dreams of Babylon 5's inhabitants and gradually gains control over many, even during waking hours. A thrall network forms, led by Deuce, who demands a quicker excavation and grows increasingly hostile toward others.

Early in the investigation Babylon 5

Trent powers up the device without authorization

Trent and a reluctant colleague decide to power up the device to accelerate the examination. They do so without informing Captain Sheridan, creating tension and a potential security breach aboard the station.

During initial examination Babylon 5 – laboratory

Sheridan and Lyta seek answers from Lyta

Sheridan and Delenn visit Lyta Alexander, who transmits a 'race memory' that provides crucial context about the artifact. The memory hints that the gate is tied to ancient Vorlon schemes and a danger from beyond human understanding.

Following the device activation Babylon 5

Backstory: Vorlons, Thirdspace and the gate

Lyta explains that Vorlons built the gate a million years ago to reach the gods, but it connects to a dangerous parallel universe called Thirdspace. The Thirdspace aliens are telepathic, violent, and seek to annihilate other life. The revelation reframes the investigation's stakes.

During Lyta's briefing Babylon 5

Vorlons' history with the gate and its containment

Long ago, Thirdspace aliens telepathically converted a small Vorlon force to fight for them, leading to a stalemate. The non-thrall Vorlons shut down the gate, but the thrall Vorlons prevented its destruction by sending the artifact into hyperspace, where it was preserved for future awakening. This history explains why the artifact could reappear and threaten Babylon 5 again.

Before reactivation Babylon 5

Lyta provides deactivation instructions

Lyta telepathically informs Captain Sheridan how to deactivate the gate, outlining a countermeasure embedded in the Vorlon telepathic code. The team prepares to use this knowledge to avert catastrophe before the device is reactivated.

Before the reactivation Babylon 5

Thirdspace activated; invasion begins

The device is reactivated and Thirdspace aliens stream out from the portal in small fighters, beginning a devastating assault on Babylon 5. The invaders’ ships are highly advanced and use deflector shields, making them extremely difficult to destroy. The telepathic influence still at work among the thralls appears to disrupt the station's defenses.

During activation and first wave Babylon 5 vicinity

Defense and battle intensify

Babylon 5's defenses are compromised as thralls fight against the station's personnel while the Thirdspace fleet presses the attack.

During the initial invasion Babylon 5

Sheridan destroys the artifact; telepathic influence ends

Sheridan deploys a thermonuclear device and destroys the artifact just as the first wave of Thirdspace heavy warships emerges. The destruction halts the mind control and the station's defenses begin to recover as the alien threat wanes. With the artifact gone, the telepathic influence ends and life on Babylon 5 returns to normal.

At the height of the invasion Babylon 5

Trent delivers final report and goes on hiatus

Trent, shaken by the artifact's effects on personnel, turns over her final report to her superiors and begins an indefinite hiatus from field work. She expresses lingering doubts about the nature of the artifact and the implications of the findings.
